Just edit the file, use plain text username and password instead of encrypted like Username: weblogic password: Weblogic1 After start the server from command line, it will encrypt again automitically. 2. remove the ManagedServerDir/data/ldap directory completely. 3: Always keep backup of files before removing it. Comment from John ( jmb1963@hotmail.co.uk) One other thing before you start deleteing files. If you have more than one domain on your network make sure that you have used a unique cluster multicast address otherwise things will get confused! Thanks a lot for your valuable comments.
